Quality Control

Our QC isn’t about “we say it’s good”—it’s about proving every step


1.Traceable Materials: You Can Verify Every Component 

Copper, jacketing, connectors—we keep supplier test reports


2.Production Checks: See the Work 

We’re transparent. If you’d like, we’ll grant you access to our production floor cameras to watch key steps:

Terminal crimping: We use automated machines.

Jacket sealing: We use heat shrink machines.The shrinked jacket is even—no bubbles. 

Final assembly: Harnesses are neatly bundled.

Custom Solutions

FromYourIdeato a Ready-to-Install Product,Here’s how we make it work: 

1. Clarify Your Needs: Our engineers asking simple questions: 

• Where will this wire harness go on your device ?

• What temperature range does it need to handle ? 

• Should it be flexible or rigid ?

• Any local compliance needs ?


2. Prototypes You Can Actually Test: No “Just a Drawing” Promises

• Length, wire gauge, and connectors match your sketch. 

• We use the connector brands you prefer (e.g., AMP, MOLEX, JST....). 


3. Scalable Production: 

Once you approve the sample, we’ll sign a Production Confirmation Sheet detailing exactlywhat goes into your harness: material brands, wire gauge, and processes.
